[msh441]

I have a ton of apps and games.

As a rule of thumb, I have taken to installing Manila/Windows tweaks (the few that let you choose), tools (SPB Backup, MyPhone, Resco registry editor/file explorer, pocketRAR, wmTorrent, task managers, Lumos, ChangeScreen), browsers (Skyfire), multimedia players and services (WunderRadio, nanoGroove,Coreplayer,Midomi) and other programs I want access to 100% of the time (MMS Converter, Bing, Google Maps, GPS Weather Radar, Marketplace/OpnMarket) in the main memory.

Games and whatever else is left (mainly music, notes, wmTorrent files, e-mail attachments, photos and all my backup .cabs) go on the storage card.

Basiclly, I install with the thought of "what could I live without", like if I were to loose/remove/switch my storage card.

That said, I'm at 46% of main memory used and 86% of a 16gig storage card (most of that is music, though).
